Love it I actually been in the neighborhood of buying a quad charger thanks for the product review and the link bud appreciate it and all the videos keep it up
Good review. Best part was the end where you're like..the reason I have faith in this is because I have the older one. That right there was the selling point for me. I've watched a few of your videos now and I'm glad to subscribe.
Great video 👍 A 100 watts per channel charger is great for 4s and below. If your trying to charge up multiple 6s or even 4s around 8000 mah your gonna need more watts. The 10amps Max is true but it's based on the cells and MAH of the battery your trying to charge so in reality it won't get up to that 10amp specification. I have found that I need a minimum 150 watts per channel and for big 6s batteries I really need 200 watts 👍
Yeah recently starter getting this problem to Got one htrc c240 duo and one t240 duo Both of them only charge at 4.5a max each when charging 7000mah 4s packs And 5-6amp on the 8000 mah 3s packs This is a big let down when getting back from work and wanna charge a few packs up and get on out before it gets dark Also mostly running Losi SRR so need 2packs at least Usually want 6packs or 3 sets witch is not possible unless I charged some the night before I guess I might be better off with 4x200w charger or 2x200w and get two? Wish there was a 1500w 6port charger available, but at what price
What charger/discharger do you recommend if I am looking for a 4-channel charger with 10A charge/5A discharge each channel? I am condition four ni-mh modules for a hybrid car so I got 28 totally, discharge speed and product quality matter the most.
That charger isnt going to discharge anything at 5A or anywhere close to it. The specs say it has a max discharge of 10W which on a 2S lipo is about 1.3A. On a 4S Lipo its only going to discharge at half that or about 660mA and a 6S is going to top out at about 450mAh. Its also a good thing that you didnt go above 8A on that 3S lipo because at 100W per channel a 3S lipo charge is going to top out at about 9A. A 2S lipo will be able to be charged at 10A but a 4S is going to be limited to 6.75A, and 6S is going to be limited to about 4.5A. Personally if I was going to spend $240 on this Id rather spend the same amount on 2x HOTA D6 Pro models. Ok sure its an extra AC cord to plug in but the specs are as good or better than this charger on AC and absolutely smokes the specs if you run the HOTAs off of DC power. On DC a pair of HOTAs have a combined Charge wattage of 1300W or 325W per channel. Lets face it theres a lot of places out there selling cheap DC power supplies so why wouldnt you take advantage of DC input at least when youre at home. 24-30V DC input is where its at. Even if you wanted an all in one unit Im not sure why youd buy this anyway. This is pretty much a direct clone of the Protek Prodigy 610 QUAD AC charger which costs the same amount. If they cost the same (and the Protek has a 20W discharge instead of 10W) why wouldnt you buy the name brand model? For me? I would not call this the best charger.
@@RoadsideRC The one thing that this charger (and Im assuming the Protek charger) has that the HOTA doesnt is the ability to take stand alone IR readings. The HOTA will read IRs during charging but thats not as convenient as the stand alone readings.
I charge enough lipo packs for a day's flying the night before. If I have to cancel or cut short a flying session, I can storage charge four packs at a time fairly quickly. These chargers are fine for up to six cell counts and modest capacity lipos used in typical small to medium sized electric powered model airplanes. People use them for many other applications within their limitations.
You nailed it, you need a charger that produces 100 watts per channel DC powered. Is this a AC spec or DC spec? The wattage sounds on point if it’s DC rated. I’ve been around the block, seen and bought chargers that trick you saying AC specs confusing DC spec. I will check it out. One Think that worries me maybe, maybe not, it being very light, scares me. That has no facts behind it as chargers technology has come a long way. I’ll check it out. Be careful with a new charger and fires. Sounds good! If I like the specs after research I’ll buy one. Thank you my man! 👍
Thanks for the feedback. I am not sure if it is a AC or DC rating. I have been using this charger for awhile now (real-life time vs UA-cam video publishing time), and it has done really well for me. No issues at all.
Hi there. How is it holding up? I'm looking for a 4 port LiPo charger, this one popped out on my screen, but the Amazon reviews are quite concerning. What do you think of it so far and how is it working for you? thanks.
Hi Troy, I purchased an EV-Peak CQ3 and ended up with the BGUAD model like you are showing. I have found that when I use the Digital Power mode, the voltage varies around what I set it to. eg. if i set it to 12.0Volts and then turn that channel on the voltage varies up and down around the 12V. ie. vari ying from about 11.8 to 12.2 random voltages but continually changing. Would you be able to setup your CQ3s to Digital Power to see if you get the same result? You have to turn the channel on to see the changing voltage. Thanks, Eric (Australia)
Is this charger made by Chinese manufacturer EV-Peak? Is it the same exact charger as the original blue and gray EV-Peak EQ-3 charger? I have the old EV-Peak 3260 80 watt per channel that is still working. I don't think that the charger actually measures cell IR, does it? Nicely detailed review.
My understanding is it is the next version of the blue EQ-3 that you are referring to. I used to have that charger - it was great also. I actually just used the IR feature this last weekend. It doesn't show it for each individual cell, it shows it for the pack.
This has pretty much identical specs compared to my Protek 610 Quad chargers. They charge plenty fast enough for me. I started with a dual Protek and quickly realized that was a bad idea. I agree 💯 about buying quality chargers and I never let me kids deal with the lipos either. I always make sure to charge in a lipo bag and store in lipo bags. I’m always careful and respect these lipo batteries. You never know when one can go up in 🔥 Great info 👊👊👍👍
Make sure that US seller will exchange defective charger during 30-day, or whatever, warranty period. Chinese EC-Peak company is not responsive . Get FPV sells the CQ3 for $160.
I got one of these, it did not come with a booklet. Anyway, i i purchased a 12v 20ah lifepo4 to use with it to field charge on the DC port.. I planned to charge the 20ah with the bquad when i returned.... i hooked it up at a mild 5 amp charge rate and c4 life charge 12:12 setting. After about 45 minutes it started flashing" "capa" instead of full or end. Is this noemal?
@@RoadsideRC so I figured it out, I sat and watched them and they go up to 4.5 then slowly goes down until all cells are balanced and at 4.2 total. Then shuts off and says fully charged!
Can this one charge nimh hv battery parts(lexus rx 450), like 8-7-7-8 cell per channel(67.2 or 76.8 volts)? Can it start charging automatically when power is on? want to make a plug in hybrid:)
But will the buttons last? I have had two multi-port chargers of this type where buttons have failed for one or more banks. P.S. COLOR CODE THOSE LEADS TO AVOID CROSS-CONNECTIONS.
That sucks for sure! I had the older model of this charger - used it for a few years without any issues with the buttons. Which leads are you talking about color coding? The main banana leads and the inputs are color coded already.
I did only balance port with the small adapters and it takes the light to get green in about 6 to 8 hours hahaha.

You mean when you put your batteries in storage mode you set this charger to storage mode and you turn it up to 10 amps I have a buddy that thinks you're trying to discharge and from what I understood if you used it discharged function on a charger you would destroy your lipos because that's how you dispose of them by discharging them ?

Interesting use case! I don't use this charger for the dame purpose you do, so a little hard to say for 100% certain. However, when I charge, it is more voltage targeted vs a change in mah. Check those settings and see what is happening.

You need to look in the settings. It has a trigger to stop at a certain capacity. Easy solve!
Using the 8000mah lipo as example,when charging at 8A,do you get same amount of run time vs charging it at a slower rate?
Yes. Charge rate does not have anything to do with capacity.
